Implications for Advisors
The historical data leans positive: TSLA has drifted higher at +28 days in two-thirds of Q3 down events. But the closest comp to today’s size — 2019’s then-record (13.6%) decline — did not recover.
- Advisors holding long TSLA positions should weigh the ~67% historical recovery odds against a wide range of outcomes — (16.6%) to +32.3% — rather than assuming a bounce is likely.
- Given today’s move is larger than any prior Q3 comp, defined-risk structures or reduced position size may be more appropriate than a straight long hold over the next 28 days.
